Spectroscopy is an analytical technique that measures the interaction between electromagnetic radiation (or other energetic probes, such as electrons or ions) and matter as a function of wavelength, frequency, or energy to obtain information about a system’s composition, structure, and dynamics. By monitoring absorption, emission, scattering, or reflection, spectroscopy reveals quantized energy levels associated with electronic, vibrational, and rotational states. Variants such as UV–Vis, infrared, Raman, nuclear magnetic resonance, and X-ray spectroscopy exploit distinct interaction mechanisms and selection rules, enabling determination of molecular identity, chemical environment, bonding characteristics, and in some cases spatial or temporal evolution of materials and biochemical systems.
This summer, Subaru Telescope will welcome a new near-infrared spectrograph, NINJA, for its first on-sky engineering observations. NINJA is a new spectrograph designed for time-critical observations of rapidly evolving cosmic ...
